Unless you play it on a phone (or another screen with the same vertical aspect ratio as a phone), you'll always have black area around the active video.
This is a good reason not to shoot in "Vertical Video": if you hold the phone sideways, you'll have a better chance of coming close to the 16x9 aspect ratio of modern TV sets. Otherwise... you gotta blow it up (zoom it in).
